[ hpa: changed the feature flag to simply X86_FEATURE_CLFLUSHOPT - if
that is what we want to report in /proc/cpuinfo anyway... ]

x86: __force_order doesn't need to be an actual variable
It being static causes over a dozen instances to be scattered
across the kernel image, with non of them ever being referenced
in any way. Making the variable extern without ever defining it
works as well - all we need is to have the compiler think the
variable is being accessed.
